Build the Windows client against the MSVC ABI while retaining clang
language support. Use vcpkg for ANGLE and libsamplerate, and build
MsQuic with its bundled static OpenSSL.
Build MsQuic's component archives instead of flattening Windows import
libraries into the monolithic archive. Use the static OpenSSL archives
supplied by the active MinGW toolchain while retaining Schannel for MSVC
and QuicTLS for Linux.
Let the active compiler locate its target root and use the restricted
ntdll import library. Provide GCC-compatible byte interlocked
operations, expose native XDP calls, and suppress expected compatibility
warnings.
Add LGProtocol as a pinned submodule and consume its KVMFR protocol
definitions throughout the client, host, IDD, OBS, and profiler.
Keep Looking Glass framebuffer helpers local while removing duplicated
protocol headers and migrating users to KVMFR-scoped types.
This brings nanosvg into the project for SVG loading and rendering.
Unfortunatly we can not at this time use a submodule for this project
until https://github.com/memononen/nanosvg/pull/214 is merged.
1. Correctly detect ON state so that host is not built as -march=native by
default.
2. Merge OFF and GENERIC options as we need at least -march=nehalem to build
properly.
